From dea55137634226fd74d5187a15dee1244ec252cb Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 11 Mar 2008 19:52:31 +0900 Subject: [PATCH] ahci: request all PCI BARs ahci is often implemented with accompanying SFF compatible interface and legacy IDE driver may attach to the legacy IO ports when the controller is already claimed by ahci and vice-versa. This patch makes ahci use pcim_iomap_regions_request_all() so that all IO regions are claimed on attach.
